The jaws of the clip 27 are held normally closed under the tension of aspring, and to that end a pulley wheel 17, slidably journalled upon therod 16, is positioned beneath the surface 21 of desk 28. A cable 12passes over the groove of pulley wheel 17, through an elongated slot 19(Fig. 2) in the desk surface 21, and terminates in a hook 31 (Fig. 6)which engages in one of the apertures 30 of the punched bracket 9 formedon the plate 8. An angle bracket 22 (Fig. 6), which is secured to theunder-side of desk 28, is adapted to receive a machine screw or bolt 32.The cable 12 is retained under tension by means of a coiled spring` 20(Fig. 6) forming a ccntinuation of said cable and anchored to the screwVbolt 32.

(left-hand) end of the clamping edge of the upper Whenever the outerblotter holder 13 is depressed, its inner righthand) end moves radiallyupwards about the rod 15, causing the fingers 45 to engage beneath theupper jaw of plate 8, imparting an upward movement to plate 8 againstthe increasing tension exerted spring 2O upon the cable 12 andconsequently upon the plate 8. Vhen pressure is removed from the outerend of bl'otter holder 13, the plate 8 is restored to its normalposition under tension of spring 20, and Athe curved lip 49 functions toclamp any loose blanks positioned thereunder.

The headblock 40 is beveled or undercut as indicated at 50, therebytending to retain the blanks secured by the clip 27 in position and inalignment.

The punched bracket 9 extends from a point adjacent an imaginarytransverse medial line extending across the .plate 8, to a pointadjacent the side wall 44. Similarly, the holespunched in the bracket 9extend from a point adjacent the'centre to a point adjacent the sidewall 44 of the pla-te 8. The hook 31 is adapted toengage with any hole30 in the punched bracket 9, and as the pulley 17 is slidably journalledupon the rod 16, the pulley may be moved so as to position the pulleyopposite the particular hole 30 in which hook 31 may happen to beengaged. A series of apertures in the angle bracket 22, each apertureadapted to receive the machine screw or bolt 32, may likewise beprovided so that the position of the machine screw may be changedrelative to the bracket 22, as desired, for the purpose of maintainingthe machine screw 32, spring 20, cable 12, pulley 16, hook 31, andaperture 30 wherein said hook may be engaged, in a plane substantiallyat right angles to bracket 9. When the tension exerted by spring 20 viacable 12 `and hook 31 is applied adjacent the imaginary transversemedial line extending across the plate 8, the pressure exerted b the lip49 upon the blanks positioned thereby the coiledV upon rod 16 asdesired,

under will be substantially uniform at all points throughout the lengthof the lip 49. )Vhen the pressure exerted by spring 20 is applied to theplate 8, off centre, the pressure exerted by the lip 49 upon the blankspositioned thereunder will vary at different points throughout thelength of the lip 49, said pressure being the least at the point mostremote from the point of application of the spring tension, so that lifthe hook 31 is inserted in the lowest aperture 30 of the angle bracket9, theV pressure exerted by the lip 49 upon the blank positionedthereunder, will be greatest adjacent the aperture 30 wherein the hookis engaged, and will gradually decrease along the length of the lip 49as we approach the upper corner adjacent the end wall 43.

The aperture in the side wall 44, through which the rod 15 isjournalled, is circular,

while the aperture 10 yin the wall 43 is elongated, so that if thepressure exerted by the spring 20 upon the plate 8 is applied adjacentthe end wall 44, there will be a tendency for the plate 8 to moveupwards until thelower portion of the-elongated slot 10 engages with therod 15, thereby eifecting a gradually increased separation between thelower jaw 2l and the lip 49 of the plate 8 or upper jaw, this separationbeing greater as we approach the end wall 43. By virtue of thesestructural features, any blank held upon the surface 21 under thepressure exerted by lip 49 of the plate 8 or upper jaw, will becomparatively loosely secured at the upper left hand corner, but heldmore and more securely in position as we approach the lower left handcorner of the blank. It will therefore be possible to detach the topblank from the remaining blanks and from the clip 27 by exerting awithdrawalmotion adjacent the right hand edge of the blank. During thisoperation the upper left hand corner of said blank willbe freed from thepressure of the curved lip 49, thereby facilitating the removal of thetop blank without tearing or mutilation.

What is claimed is:

1. In a desk clip for holding loose leaf blanks and in combination, asupporting membercomprising one jaw of the clip, a second member havingdepending side walls having apertures therein for pivotally mountingsaid second member with respect to said rst member, one of saidapertures being larger than the other to permit said members to applydifferent pressures to different portions of one margin of said blanks,and means secured to said second member at a point offset from itsmedial line for exerting said pressure.

2. In a desk clip according to claim 1 characterized in this that saidmeans is a coiled spring,

one end of which is connected to the second member and the otherr end oiwhich is connected to the supporting member.

3. A desk clip Jfor holding loose leaf blanks comprising a pair of jawmembers pivotally connected at two points, the connection at one pointbeing so formed as to permit relative movement of the jaw members in adirection transverse to the pivotal axis, and means f tending to forcethe jaw members into gripping engagement against the loose leaf blanksto be held thereby and co-o erating with said pivotal connection to prouce greater pressure between the gripping faces of the jaw members atone point than at other points. 4. A desk clip Vfor loose leaf blankscomprising a supporting member constituting one jaw of the clip, asecond member constituting the other jaw of the clip and supported bythe supporting member at two points to form a pivotal connectiontherebetween, the connection at one point being such as to permitmovement of the second member in a direction transverse to the pivotalaxis, and y means for applying pressure to the secon member at a singlepoint tending to close the jaws with graduated pressure along thegripping faces thereof.

In witness whereof, I hereunto subscribe my name this th day ofSeptember 1929. 30 WILLIAM F. CASSEDY,JR.
